To the above ends my invention consists The spool 2 is preferably formedof metal in the construction, arrangement, and comand consists of acylindrical hollow core or bination of parts, to be hereinafterdescribed, spindle 11, upon which the ribbon 12 may be and particularlypointed out in the appended wound, and ends orflanges 13, which may be70 claims. connected to the core in any suitable man- In theaccompanying drawings, wherein ner.

In Fig. 6 the spool 2 is made of plain ey- Iindrical form withoutflanges, and its ends are journaled to revolve in plain holes 7, formedin the lower portions of the depending arms 6, carried by the cover 3 ofthe box.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. In a device of the character specified, the combination of a box, acover therefor, oppositely-arranged supports depending from said coverwithin the box, and aribbon-spool revolubly sustained by said supports.

2. In a device of the character specified, the combination of a box, acover therefor, oppositely-arranged spreadable supports depending fromsaid cover within the box, and a ribbon-spool revolubly sustained bysaid supports, and adapted to be readily attached to and detachedtherefrom.

3. In a device of the character specified, the combination of a box, acover therefor, oppositely-arranged supports depending from said coverwithin the box, and a ribbon-spool revolubly sustained by said supports,one of the parts having horizontal journals for the spool and the otherbearings for said journals.

4. In a device of the character specified, the combination of a box, aremovable cover therefor, oppositely-disposed bearing-studs carried bysaid cover, and a spool having bearing-openings for the reception ofsaid studs, whereby the spool may be removed with the cover.

5. In a device of the character specified, the combination of a box, aremovable cover therefor,a springsupportcarried by the cover, and aspool revoluble upon said support and removable with said cover andadapted to be removed from said spring-support.

6. In a device of the character specified, the combination of a box, aremovable cover therefor, depending resilient supporting-ears carried bythe cover, and a spool carried by and revoluble between saidsupporting-ears and removable with said cover.

7. In a device of the character specified, the combination of a box, aremovable cover therefor,supporting-ears carried by said cover andprojecting into said box and having oppositely-disposed bearing-studsthereon, and a spool having openings within which the studs are adaptedto be seated.

S. In a device of the character specified, the combination of a box, aremovable cover therefor,supporting-ears carried by said cover andprojecting into said box and having oppositely-disposed bearing-studsthereon, a ribbon-spool having openings within which the bearing-studsare adapted to be seated, and a spring for maintaining said ears againstaccidental separation so as to prevent the studs from being accidentallydisplaced from their bearing-openings in the spool.

9. In a device of the character specified, the combination of animperforate box, an imperforate cover therefor, oppositely-disposedsupporting-ears carried by said cover, a spool detachably carried by andrevoluble between said ears and removable from the box with the cover.

10. In a device of the character specified, the combination of animperforate box, a removable imperforate cover therefor, supporting-earscarried by said cover and projecting into said box and havingbearing-studs thereon, a ribbon-spool having openings for the receptionof said bearing-studs to revolubly support the spool, and means forpreventing accidental displacement of the bearing-studs from theirbearings in the spool, whereby the spool may be removed from the boxwith the cover.

11. In a device of the character specified, the combination of a box, aremovable cover therefor, a supporting-piece carried by and removablefrom said cover, resilient ears carried by said supporting-piece andprojecting into said box, oppositely-disposed bearingstuds on said ears,and a ribbon-spool having a cylindrical spindle in which saidbearingstuds are adapted to be seated, so that the spool is free torevolve between said ears and so that the spool may be removed with thecover.
